Ideas for Covering Exterior Brick Walls

When considering exterior brick wall treatments, the default assumption is often a desire for a complete transformation. However, a more nuanced approach reveals that “covering” can encompass a range of modifications, from complete concealment to subtle enhancements. This guide explores practical ideas to cover brick wall outside, focusing on both aesthetic and functional outcomes, while critically examining common assumptions.

ideas to cover brick wall outside: Evaluating Exterior Brick Wall Coverings: A Contrarian View

Before committing to any method, a rigorous evaluation of your goals and the existing brick is crucial. The primary objective is often visual appeal, but a contrarian perspective suggests questioning the necessity of complete concealment and prioritizing the preservation of the brick’s inherent structural and aesthetic value.

Principle-Level Explanation: The Material Science of Coverage and Its Pitfalls

The effectiveness and longevity of any exterior brick covering depend on understanding the fundamental properties of both the brick and the chosen material. Brick is porous and breathable, allowing moisture vapor to escape. Materials that impede this natural respiration can lead to moisture entrapment, freeze-thaw damage, efflorescence (salt deposits), and ultimately, structural degradation.

Permeability: The ability of a material to allow water vapor to pass through. High permeability coverings (e.g., certain breathable paints, limewash) are generally compatible with brick. Impermeable materials, however, can be detrimental.
Adhesion: The bond between the covering and the brick substrate. Poor adhesion leads to delamination and failure, often exacerbated by moisture issues.
Durability: Resistance to UV radiation, moisture, temperature fluctuations, and physical impact. The durability of the brick itself is often underestimated compared to applied finishes.
Maintenance: The effort and cost required to keep the covering looking its best. Consider that the brick may require less maintenance than many applied finishes.

Counterpoint: The Unseen Cost of “Perfect” Coverage

Many homeowners opt for complete concealment, believing it offers a pristine, maintenance-free facade. However, this often overlooks the potential for hidden damage. Encasing brick in impermeable materials like vinyl siding or certain synthetic stucco systems can trap moisture. This trapped moisture can freeze and expand in colder climates, causing spalling (surface flaking) of the brick and mortar. Furthermore, the original brickwork, if sound, represents a durable and historically significant element that is irreversibly altered. The “perfect” facade might be masking deeper structural issues.

Practical Ideas to Cover Brick Wall Outside: Beyond Simple Concealment

When selecting ideas to cover brick wall outside, a balanced approach considers both aesthetics and the brick’s inherent properties. We will explore options that range from enhancing the existing brick to providing a new surface.

Option 1: Strategic Painting and Staining

Painting brick is a common choice, but it requires careful execution and a critical eye towards breathability.

For a significant aesthetic transformation, consider specialized masonry paints. These are formulated to be breathable, which is crucial for the longevity of your brickwork.

These are more traditional and breathable alternatives to acrylic paints, offering a distinct aesthetic.

Mechanism: A natural mineral-based coating that chemically bonds with the masonry. It diffuses color rather than forming a solid film.
Pros: Highly breathable, creates a soft, matte, aged aesthetic, environmentally friendly, can be reapplied over itself.
Cons: Limited color palette compared to acrylics, application can be more involved, may require more frequent reapplication over decades.
Decision Criteria: Desired aesthetic (soft, diffused color) and a commitment to breathability. This is ideal for historic properties or those seeking a heritage look.
CTA: Obtain samples and test on an inconspicuous area to evaluate color and finish before full application. Note how it weathers over time.

Option 3: Stucco or Render Systems for a Uniform Surface

These offer a smooth or textured finish over the brick, effectively creating a new facade.

If you’re aiming for a uniform surface and want to conceal imperfections, stucco or render systems are a viable option. These can create a smooth or textured finish over the existing brick.

No products found.

Mechanism: Applying a cementitious or lime-based plaster.
Pros: Creates a uniform, modern or traditional look, can conceal significant brick imperfections, offers some insulation value (depending on system).
Cons: Can be expensive, requires skilled labor, potential for cracking if not properly installed with expansion joints, can trap moisture if not a breathable system.
Decision Criteria: Desire for a completely uniform surface and budget. This is a significant alteration.
CTA: Verify that the chosen stucco system is rated for exterior use on masonry and inquire about the manufacturer’s recommendations for moisture management and expansion joints.

Option 4: Cladding with Wood or Composite Panels

This involves attaching a new facade over the brick, transforming the home’s appearance.

Mechanism: Installing a rainscreen system with vertical or horizontal panels. This creates a critical air gap for drainage and ventilation.
Pros: Wide range of aesthetic options (wood grain, modern metal, fiber cement), can significantly update the home’s appearance, can provide an additional layer of insulation.
Cons: Most expensive option, requires careful detailing to prevent moisture intrusion behind the cladding, can alter the original architectural character.
Decision Criteria: Budget, desired modern aesthetic, and the ability to create a proper rainscreen gap. This is a substantial investment.
CTA: Work with a qualified architect or contractor to ensure the rainscreen system is designed to meet local building codes and effectively manage moisture.

Common Myths About Covering Brick Walls

Debunking common misconceptions is vital for informed decision-making, especially when considering the long-term implications.

Myth 1: Any paint can be used on exterior brick.
Correction: Standard latex or oil-based paints can trap moisture, leading to premature failure of the brick and coating. Only specialized masonry paints designed for breathability should be used. These often have specific formulations to allow vapor transmission, preventing the buildup that causes spalling.
Myth 2: Covering brick always increases home value.
Correction: While a well-executed renovation can enhance curb appeal, covering historically significant or well-maintained brickwork with a less durable or aesthetically incongruous material can actually decrease value for buyers who appreciate original character. Thorough market research and consultation with real estate professionals are recommended, as a poorly chosen covering can detract from the property’s appeal and perceived quality.

Expert Tips for Covering Exterior Brick

Applying these insights can prevent costly mistakes and ensure a successful outcome.

Tip 1: Prioritize Breathability Above All Else.
Actionable Step: When selecting a paint, stain, or render, confirm its vapor permeability rating. Look for products specifically designed for masonry that allow moisture to escape. For example, products with a high Water Vapor Transmission (WVT) rate are preferable.
Common Mistake to Avoid: Using standard exterior paints or non-breathable synthetic stucco systems that seal in moisture, leading to efflorescence, spalling, and potential structural damage over time.
Tip 2: Thorough Surface Preparation is Non-Negotiable for Longevity.
Actionable Step: Clean the brick thoroughly using appropriate methods (e.g., pressure washing at a safe distance, chemical cleaning) and allow it to dry completely for several days, or even weeks in humid conditions, before applying any coating or cladding.
Common Mistake to Avoid: Applying new materials over dirt, efflorescence, loose mortar, or damp surfaces, which compromises adhesion and leads to early failure, requiring costly repairs.
Tip 3: Consider the Long-Term Maintenance Commitment and Reversibility.
Actionable Step: Research the expected lifespan and maintenance requirements for each covering option. Factor in potential costs for cleaning, repair, or eventual reapplication. Also, consider how easily the covering can be removed in the future should tastes or needs change.
Common Mistake to Avoid: Opting for a visually appealing but high-maintenance solution without understanding the ongoing effort and expense involved, or choosing a permanent covering that limits future aesthetic choices.
